> it is more difficult to sell a very expensive home vs a cheaper one

I don't know where you are, but in Bay Area this is not true. And even for mega-expensive homes that don't sell as fast, the agent can't really accelerate this much -- certainly not commensurate to the giant commission they receive.

I'm in the bay area. I'm not concerned about arguing over edge cases I'm speaking generally that very expensive homes are inherently more difficult to sell than cheaper ones. You're just pointing out in certain areas homes that are "expensive" in other cities are just average to a relatively large pool of high income buyers.

With expensive luxury homes you have a smaller buyer pool and more discerning buyers and they will sit on the market longer than cheaper homes. So I still stand by the fact that they are going to be more difficult to sell than a cheaper one for fairly straightforward reasons.

How is a $100k house different from a $600k house. 4m is a different class of customer.
